Which phrase accurately completes: "His boss won't .................................. lateness"?

The phrase that accurately completes "His boss won't ..." is "put up with." This phrase conveys a clear meaning of endurance or acceptance of something undesirable. In a workplace context, saying that a boss won't "put up with" lateness implies that the boss has a low tolerance for tardiness and will not tolerate it as part of acceptable behavior.

While the other phrases also relate to the idea of not accepting lateness, "put up with" specifically emphasizes the idea of enduring or managing a certain behavior but refusing to accept it over time. It captures a sense of patience that has limits, which aligns well with the context of a boss's expectations regarding punctuality.

The other phrases, while they could be considered correct in some contexts, do not convey the same nuance. For example, "allow for" suggests making allowances or adjustments and does not directly imply a rejection of the behavior, and "accept the fact of" indicates recognition of lateness rather than a refusal to tolerate it. Similarly, "tolerate this behavior" supports the idea of enduring something undesirable, but it sounds a bit more formal and less colloquial compared to "put up with," which is more commonly used in everyday conversations about personal limits or boundaries.
